Abstract: The invention belongs to the technical field of vehicles, and relates to a vehicle moving across a water-air interface. The vehicle includes a cabin base, a transformable sail, a reefing mechanism and a reefing control mechanism. By means of the reefing mechanism and the transformable sail, the present invention can freely switch between a surface navigation mode and an underwater navigation mode.

Abstract: A thrust reversal emergency jettison device for an underwater vehicle includes a thrust reversal mechanism. The thrust reversal mechanism includes a casing and a gas reaction compartment provided in the casing; the gas reaction compartment communicates with a gas passage in a shell of the casing through a gas pipe; and a bottom end cover is provided at a bottom of the gas reaction compartment, and the bottom end cover is hermetically connected with the gas reaction compartment through a cylinder mechanism, and falls off automatically when a gas pressure in the gas reaction compartment increases. Compared with the prior art, the present invention can provide a reverse thrust for an underwater vehicle in an emergency, help the underwater vehicle to ascend, and improve safety.
